SPECIFICATION forming part of Letters Patent No. 652,754, dated July 3,1966.

Application filed June 24, 1899. Serial No. 721,681. (No model.)

To all whom, it may concern:

Be it known that I, EDWARD DAVIS, of Boston, in the county of Suffolkand State of Massachusetts, haveinv'ented certain new and usefulImprovements in Registers, of which the following is a specification.

This invention relates to devices for recording a message on the tape orrecord-strip of a register, such as the registers or receivinginstruments employed in municipal signaling and other systems.

The invention involves the use of a perforating-punch in place of themarking devices ordinarily employed heretofore; and it consists in thenovel features of construction and arrangement which I shall now proceedto describe and claim.

Of the accompanying drawings, Figure 1 represents a top plan view of aregister constructed in accordance with my invention. Fig. 2 representsa reverse plan view thereof. Fig. 3 represents an end elevation. Fig. 4rep-' resents a transverse vertical section thereof. Fig. 5 represents asection on the line 5 5 of Fig. 4:- Fig. 6 represents a detail sectionon the line 6 6 of Fig. 4:.

The same reference characters indicate the same parts in all thefigures.

Referring to the drawings, adesignates a fiat base composed of asuitable insulating material, such as hard rubber, and b designates ametal frame mounted'thereon and containing a clock-train b, which isadapted to be actuated by a weight and cord or a spring and is providedwith a suitable retarding-escapement.

The register, as herein illustrated, is constructed as to certain of itsparts on the principle of the register described in Letters Patent ofthe United States No. 620,703, granted to me March 7, 1899, to whichreference may be had for detailed exposition of the operation of saidparts. The said parts, as illustrated, include devices as follows: d dare a series of electromagnets-four in number in the presentinstancemounted beneath the base a and having their pole-pieces exposedabove said base. The armatures of said magnets are mounted onfriction-pivots and are provided with vertical arms a c, adapted tocoact with a series of metal disks 0 c, mountcycle.

ed upon a shaft 0 in the control of a series of alarm-circuits. Theshaft 0 is rotated by the clock-train b, which is synchronized with theinstruments at the transmitting-stations. The actuation of a transmitterstarts the clock-train]? in motion, and the disks 0 complete onerevolution in the same time that the contact device in the transmittercompletes a The disks ccan be fixed at different relative rotarypositions 011 the shaft 0 and the impulses from the transmitter received.through its corresponding magnet of the series (Z (Z, will cause or notcause an audible alarm to be sounded, according to the adjustment of thecorresponding disk 0.

The several electromagnets d d are connected in series, respectively,with a group of four electromagnets e e, mounted below the base a, withtheir pole-pieces directed downwardly. The two magnets (Z c of any pairare connected directly or through a relay to the transmittinginstrument, and each receives the same impulses. I

e 6 represent the armatures of the magnet-s c, said armatures beingpivoted by flexible springs e to the magnet-frames and having their freeends normally supported by stop-screws e 6 The free ends of the severalarmatures converge and are alined beneath a fixed plate f, which has aseries of slots f, Fig. 6, guiding the lower ends of a of saidrock-frame are secured to a shaft i journaled in suitable bearings andcarrying at its end an arm i A pin i on the end of said arm is normallyengaged with the end of an arm i on an arbor of the clock-train b,

and a second pin 1' normally enters a notch & cut in the edge of a disk1 mounted on one of the magnets 2 causes it to attract its armature andlift one of the punch-bars g, which in turn elevates the cross-bar t" torelease the clock-train. The disk i preferably makes one revolution toone of the circuitcontroller disks c, and the arm 1' makes'a greaternumbersay five. WVhen the notch '6 again comes around, the pin 2' fallsinto it, and the pin 1' stops the arm i and arrests further movement ofthe clock-train. During the movement of the clock-train the message issent in'and recorded on the tape in the manner which I shall now proceedto describe.

The tape or record-strip is unwound from a suitable reel (not shown) andpasses between two guide-rolls 7c 70, then over the tops of thepunch-bars g g, and between two feedrollsjj, the upper one of which ismounted on the end of an arbor of the clock-train b and positivelyrotated thereby, while the under one 3" is a presser-roll. During themovement of the clock-train the tape, which is represented by the letteron in Fig. 6, is

' fed along through the register over the tops f 7t in the plates f hact as guides.

of the punch-bars g. The top ends of said bars,as shown in the drawings,are pointed to perforate the tape, and opposed to said ends, on theupper side of the tape, is an abutmentroll 0, loosely mounted inhearings on suitable standards 0 0. The said roll is formed with anumber of circumferential grooves 0 0 above the ends of the respectivepunchbars. The cylindrical periphery of the roll affords an abutment forthe tape, and the grooves 0 receive the ends of the punch-bars when thelatter are elevated, whereby the ends of said bars act as punches toperforate the tape in cooperation with the abutmentroll.

The important novel feature of my invention consists in providing for alongitudinal travel of the punches with the tape or recordstrip whenthey have been actuated to perforate said tape. In the arrangement shownin the drawings I accomplish this result by providing a fixedguide-plate h for the upper ends of the punch-bars g g, the said platehaving a series of slots 7t h, through which the punch-bars project andwhich are elongated in the direction of travel of the tape. Thepunch-bars are normally held against the rear ends of the slots h bymeans of light springs 9 attached to the hooked ends of the plates 9.When one of the magnets 6 receives an impulse, its armature lifts thecorresponding punoh-bar g in a substantiallyvertical path and causes itto perforate the tape, whereupon the said bar g, by reason of thelongitudinal travel of the tape at, partakes of a limited oscillatorymovement during the existence of the impulse. The normal retractedposition of the parts is represented in Fig. 5, and the position of thepunch during the existence of an impulse and at the limit of itsoscillatory movement is represented in Fig. 6. During the verticalmovement of the punch-bar the edges of the slots During the oscillatorymovement of the bar the edges of the upper slot 72/ act as a guide,while the end of the lower slot f acts as a fulcrum, the length of saidslotf being substantially equal to that of the width of the bar 9, withsufficient play to allow for free vertical movement of said bar. Theimpulses from the transmitter will preferably be regulated as toduration so that they terminate during the period of the longitudinaltravel of the punches. When the impulse in the magnet ceases, itsarmature and the punch-bar fall by their own weight, and the punch-baris retracted by its spring 9 thereby causing it to resume its initialposition. The next impulse in the magnet will then cause the punchbar toperforate the tape in a new place. The resulting impression on the tapeis a series of holes or perforations having the shape of the perforatingportion of the punch. Then the punch is brought substantially to apoint, as described, the perforations will be a series of dots. By thedescribed provisions for the longitudinal travel of the punchretardation of the tape is avoided and a perfect record is obtainedthereon, agreeing with the message sent from the transmitter.

I do not confine myself to the exact details of construction andarrangement hereinbefore described, as the same maybe variously modifiedwithout departing from the spirit of my invention, nor is the inventionnecessarily limited to employment in connection with registers such asthe one described in my patent hereinbefore alluded to and illustratedpartly in substance in the present drawings.
